First and foremost, I’m not a cyclist so please treat me as someone with little basic knowledge.
In short, have been using the HR2VP app with an HR strap and cadence sensor on my spin bike. Whilst ok, its just limited. But has proved to me that I’d enjoy Zwift long term. So…
Decided to go ahead and get a smart trainer (Wahoo Kickr Core). But a bit confused. It comes with a Shimano 11 speed cassette. That means very little to me till I read up before ordering.
The bike I have is a mountain bike with a 6 speed cassette.
Without any knowledge - surely I connect up a 6 speed to the 11 speed and away I go. Apparently not.
So the reason for the post is to ask what I need.
Here is my kid’s 10 speed cassette.
So… would my mountain bike work with a Kickr, or do I need to match up the cassette. If I do that, then would my 9 year old son by able to then whip off his back wheel and use his 10 speed cassette.
Or do I need a 6 speed cassette for my mountain bike and then a separate 10 speed cassette for my son’s bike?
If my mountain bike is not suitable, why not? Do I need a new bike? Do all 11 speed cassettes match, or do teeth on smallest and largest cogs make a difference?
As I say, I’m a newbie, I do like Zwift and want to do races primarily, but also some workouts at times too - but mainly racing. I’m likely a Cat D rider.
What I’m most worried about is buying the Kickr Core at £600, then finding I need a new £350 bike. The £600 is a huge expense for, what will be, a hobby to keep fit. I just dont want any hidden costs, mistakes etc.
